Question

As atoms gain energy, they move faster and slide past one another more easily. Atoms at the surface of the substance overcome attractions to nearby atoms and break free of the surface.

Which change of state is taking place?

liquid to gas
gas to liquid
liquid to solid
solid to liquid

Answer 1

The change of state taking place is **liquid to gas**. This process is known as **evaporation** or **vaporization**, where atoms or molecules in a liquid gain enough energy to overcome intermolecular attractions and transition into the gaseous state.
